=Polarization Measurements=

Gradually this will become instructions to take and analyze data to determine the laser polarization for the Hall C Compton.

==Taking Data: Labview Program==



==Data Analysis==

#  Use winscp on cpslow to copy data across to the cdaq cluster

====Transfer function data in 2D mode====

*  use ../fit/compilealldata_3D.pl to put a single channel vs 2D indep. variables
** eg. ''../fit/compilealldata_3D.pl TFscanHiResEntrance_Jul13_2012 output/TFscanHiResEntrance_Jul13_2012_RRPD output/TFscanHiResEntrance_Jul13_2012_RPD''
*  use ../fit/TF_constant_subtract.pl to remove the pedestal
** eg. ''../fit/TF_constant_subtract.pl TFscanHiResEntrance_Jul13_2012_RRPD 32755 TFscanHiResEntrance_Jul13_2012_RRPD_constsub''
